Only some VOIP calls are routed over the internet. Most calls, while digital, are still routed over the proprietary networks owned & operated by the major telcos.

The internet is a packet switched network, which means data is sent in packets, and it’s possible for packets to end up at their destination out of order. Two packets sent from the same starting point to the destination could theoretically go over completely different routes due to congestion, etc. The destination is responsible for putting the packets back together properly. Packets can also get delayed if other higher priority packets come along. It’s for reasons like these that both voice & video on the internet can occasionally freeze, stutter, etc. Granted the capacity & reliability of the internet has improved greatly over time so these things happen less and less often. But the fact still remains that a packet switched network isn’t optimal for real time communication.

Telephone networks on the other hand are circuit switched networks. When you are talking to somebody on a telephone then there is a dedicated circuit path between you and the other person. Each piece of the path between the two of you has a hard limit of the number of simultaneous calls it can handle, which ensures it always has the capacity to serve your particular call. If a circuit between two points is maxed out then the telephone exchange may try to route your call via a different path, or you may just end up with a busy signal.

Packet switched networks also don’t have those hard limits that circuit switched networks do. So packet switched networks can get overwhelmed (think DoS attacks) which can also lead to outages.

Next up, you’re going to have to register your drill press, lathe, etc.

Fuck that site that requires you to click through 21 individual pages instead of using just one page for the list.

It’s been literally a couple decades now but I once had to troubleshoot multiple RAID failures in a number of identical servers that were all running 6 disk RAID-5. Long story short the power supplies in each server was slowly losing its ability to power all the drives at the same time, so random drives started throwing errors. By the time we figured out the root cause, most of the drives had generated enough errors that the RAID controller couldn’t rebuild the volumes.

So, no, as others have said RAID is not a backup and should never be treated as such. A single point of failure like the power supply can easily cause the loss of the entire volume without warning.

I had a few AC Pros in a 110+ year old house where other AP’s had issues with all the plaster & lathe walls. They worked great. I also have a couple of them installed at a non-profit org I volunteer with and everybody is very happy with how they work there as well.

After moving from that first house to a new one with a bigger footprint I upgraded to a pair of their U6 mesh AP’s, one at each end of the house. Never had any issues with them.

So how would you use it to solve this problem? There still needs to be some sort of foolproof way of saying “person X is only 14 years old”.

president or secretary of a recognised organisation

What constitutes a “recognized organization”? That sounds rather open to interpretation…

Back in the 90’s I worked for a guy whose first name is “H”.

DigiCert recently was forced to invalidate something like 50,000 of their DNS-challenge based certs because of a bug in their system, and they gave companies like mine only 24 hours to renew them before invalidating the old ones…

My employer had an EV cert for years on our primary domain. The C-suites, etc. thought it was important. Then one of our engineers who focuses on SEO demonstrated how the EV cert slowed down page loads enough that search engines like Google might take notice. Apparently EV certs trigger an additional lookup by the browser to confirm the extended validity.

Once the powers-that-be understood that the EV cert wasn’t offering any additional usefulness, and might be impacting our SEO performance (however small) they had us get rid of it and use a good old OV cert instead.

If you have ssh open to the world then it’s better to disable root logins entirely and also disable passwords, relying on ssh keys instead.

Port 22 is the default SSH port and it receives a TON of malicious traffic any time it’s open to the whole internet. 20 years ago I saw a newly installed server with a weak root password get infected by an IP address in China less than an hour after being connected to the open internet.

With all the bots out there these days it would probably take a lot less time if we ran the same experiment again.

Depends on the content. My employers sites are a good mix of images, static, and dynamic content, and we rely heavily on Akamai. Their caching of our images offloads a huge amount of work from our origins. We also use their Image Manager tool to optimize a lot of the images seamlessly, which adds further optimization. Their WAF and other security tools are also very impressive.

She talks about it in this video.

I don’t understand why Cloudflare gets bashed so much over this… EVERY CDN out there does exactly the same thing. It’s how CDN’s work. Whether it’s Akamai, AWS, Google Cloud CDN, Fastly, Microsoft Azure CDN, or some other provider, they all do the same thing. In order to operate properly they need access to unencrypted content so that they can determine how to cache it properly and serve it from those caches instead of always going back to your origin server.

My employer uses both Akamai and AWS, and we’re well aware of this fact and what it means.

My employer has a pretty large presence in AWS. We finished migrating to Amazon’s Corretto (based on openjdk) months ago. It was pretty painless given we already use Amazon’s Linux distros.
